Abstract: A device for bacterial culture and assay comprises a cover having a top surface and an upper wall; a plate having a bottom surface and a lower wall, wherein a closed space is formed between the cover and the plate by engaging the cover with and the plate; and a paper strip with a uniform material, and fixed to the cover, wherein the paper strip is used to absorb a desired liquid, and the closed space is used to contain a culture medium.

Abstract: A detection device applied for detecting body fluids includes a substrate and a plurality of anti-growth factor antibodies. The substrate includes at least one reaction portion. The reaction portion includes a fiber-based material. Anti-growth factor antibodies are disposed on the fiber-based material. The present invention further provides a detection strip and a detection system for detecting body fluids. The present invention is advantageous for easy operation, lower amount of reagents and rapid analysis.

Abstract: A chromatography filter paper-based ELISA includes following steps: providing a chromatography filter paper plate provided with a plurality of independent hydrophilic regions defined by at least one hydrophobic region; immobilizing an antigen of a sample onto one of the hydrophilic regions of the chromatography filter paper plate; and detecting the antigen with an ELISA process, wherein an antibody used in the ELISA process is a monoclonal antibody. The present invention has advantages in lower amount of loaded sample, higher sensitivity and rapid analysis in comparison to conventional ELISA.
